46 THE SCOTTISH NATURALIST 



girths, or the leanest whales, appear to have occurred in 1910 

 in the case of the males, and in 1911 in the case of the 

 females. I have given a good deal of time to the problem, 

 but I cannot draw a clear and intelligible story out of it ; 

 and I see no such prospect of useful results as to lead me to 

 carry it further. 



A Summary of the Seasonal Abundance of the several Species. 



It might perhaps be useful, but it would take too much 

 space, to bring together in tabular form our chief results for 

 all the several species of whales. I will rest content with a 

 single small table, showing the differences between the 

 species in regard to their season of abundance that is to 

 say, the percentage proportion of the whole catch obtained 

 during the several calendar months :
